Please help! Viruses won’t leave.

So I had noticed these ads have poped up for a while. Not thinking too much of them. But now I really noticed they’ve been getting more aggressive. Every time I open chrome it changes my search engine to secure search so mcafee web advisor says it is blocked. So I change it back to google. Also when I search things these adventurefeed links pop on top and cookies and links were blocked. Pages would just open like crazy. I can’t even use internet explorer because of how bad it is. I scan my computer with mcafee and nothing is spotted. I’m really worried. Can someone give me advice on where to check?

I tried uninstalling some suspicious apps and reinstalling chrome with no luck.

Re: Please help! Viruses won’t leave.

So I’ve removed some suspicious programs and used Malwarefox to find some problems. I’ve erased them and so far so good with chrome with only this cookie showing up in picture. I’m afraid of opening internet explorer to trigger unwanted things. I really don’t want to start fresh because of some work files. What’s another precaution action would you recommend besides refresh windows
